ABSTRACT:
The aim of the invention is to provide a simple and compact design as well as a safe operation of a connection coupling (10) for transferring gaseous and/or liquid fluids, particularly for filling vehicle fuel tanks, comprising an inlet area (12), which is provided with an inlet valve (45), connected to a supply line (12′) and to a ventilating line (12″), and which has a pressure compensation space (44) and a ventilating valve (35). To this end, the invention provides that the ventilating valve (35) is formed by a sealing disc (24) that can be displaced in a controlled manner up to and away from the inlet valve (45) in an axial direction of the connection coupling (10).
